ByteCountInputStream
public class ByteCountInputStream extends FilterInputStream (Code)
	A FilterInputStream which will keep track of the number of bytes read from the underlying stream. Callers who want to know how many bytes have been read should attach a ChangeListener and call getCount() whenever a change event is fired. If no ChangeListeners are attached then this stream will not fire events. This improves performance by only firing events when at least one object is expecting them. author: Anthony Eden

Constructor Summary
public	ByteCountInputStream(InputStream in) Construct a new ByteCountInputStream.

Method Summary
public void	addChangeListener(ChangeListener l) Add a ChangeListener.
protected void	fireStateChanged() Fire a ChangeEvent.
protected synchronized ArrayList	getChangeListeners() Get a List of attached ChangeListeners.
public long	getCount() Get the number of bytes read so far.
public int	read(byte[] buffer) Fill the buffer with bytes until the buffer is full, the stream blocks, or until the end of the stream.
public int	read(byte[] buffer, int offset, int length) Fill the buffer with bytes starting at the given offset of the buffer and reading for `length` number of bytes.
public int	read() Read one byte.
public void	removeChangeListener(ChangeListener l) Remove the ChangeListener.
